As far as non-clustered indexes are concerned, 2005 allows 249 of them to be created while 2008 allows 999 non-clustered indexes. To add to that, it is not always the case that the query can be optimized further by simply creating an index on a column. SQL Server provides us with two main types of indexes, the Clustered index that stores the actual data rows of the table at the leaf level of the index, in addition to controlling the sorting criteria of the data within the data pages and the order of the pages itself, based on the clustered index key. This is the reason behind the ability to create only one clustered index on each table. One file group in each database operates as the default file group. When SQL Server allocates a page to a table or index for which no file group was specified when they were created, the pages are allocated from default file group. To switch the default file group from one file group to another file group,

Jun 15, 2011 SQL Server DBAs know that indexes in databases are very similar to indexes in libraries. An index in a database is a structure associated with  Clustered Index Architecture. In SQL Server, indexes are organized as B-Trees. Each page in an index B-tree is called an index node. The top node of the B-tree is called the root node. The bottom nodes in the index are called the leaf nodes. Any index levels between the root and the leaf nodes are collectively known as intermediate levels.
